The Classic 'Abbey Road' Song That Featured Solos From All 4 Beatles — Even Ringo
While The Beatles didn’t go into Abbey Road (1969) declaring it to be their final album, it certainly felt that way to the band members (and producer George Martin). In the previous year and a half, they’d had so many battles in the studio it was difficult to keep track of them.
If Ringo walking out on the band wasn’t a giant red flag, then John Lennon and Paul McCartney’s near-brawl had to be. Then there was the actual fight between John and George Harrison, as well as the fact the band’s Grammy-winning engineer quit during The White Album (1968) sessions.
In short, no one could have been shocked when John told the other Beatles he was quitting a month after they completed Abbey Road. As far as the band’s final statement went, the Fab Four had already made one with the medley on the second side of its last studio album.
